氣動熱燒蝕 的英文怎麼說
中文拼音 [qìdòngrèshāoshí]
氣動熱燒蝕
英文
aerothermal ablation-
The missile with its radome is at high temperature during the entrance. due to aerodynamics heating process, the high temperature cause air ionization and ablation of the radome, so the radome is at unsymmetrical heat environment, its electrical properties vary with different parts of the radome
導彈在再入過程中,由於空氣動力加熱效應,引起空氣電離和天線罩表面被燒蝕,因此,天線罩處于不對稱熱環境中,它各部分的介電性能不同。An experiment system simulated afterburner oxygen - riched condition was established. the system was composed of ablation test motor, gas supply pipeline and measurement and control system
該系統由富氧燒蝕發動機、氣路系統和測控系統組成,能夠模擬固沖發動機二次燃燒室富氧環境,進行絕熱層材料燒蝕試驗。Thirdly, this dissertation briefly introduces the engineering estimation method of the aerodynamic heat and supplies the simplified formulas. not considering the rejection, the ablation and some other factors, the author calculates the stagnation heat flux and the non - stagnation field heat flux distribution of some fly situation as the example aerodynamic heat environment. finally, by using the ansys program, the thermal vibration characters of the plate and missile body structures with different materials is analyzed
這一方法提高了熱振動的分析效率;第三,簡要的介紹了工程上計算氣動熟的估算方法及熱流密度計算的簡化公式,在不考慮燒蝕以及質量引射等影響下,本文計算了幾種飛行條件下駐點和非駐點區的熱流密度分佈,作為本論文算例的氣動加熱環境。
